2018 ROUSH PHASE 2 HEATSOAK

[acemastr]

I own a 2016 Roush Stage 3 Mustang.
Doesn’t the gage cluster on a Roush Mustang show the IAT2 temps as Cylinder head Temp?

These temps seem to be close to the water temperature.

No, that's iat, pre blower.

Based the posts here I believe the IAT1 was pre-blower and IAT2 was post-blower.
Does Post-blower temp equal or similar to the cylinder head temp?

No, well, I certainly hope not! With my upgraded heart exchanger mine generally sits 30f over iat1 when cruising, if your IAT2 is 190+ then there's a problem.

IAT1 is measured at the MAF Sensor.
IAT2 is the discharge air temperature post supercharger and intercooler and pre-combustion chamber.

based on a stock Roush heat exchanger the IAT1 at 100f+ I see my Cylinder head temps at +200f.

My IC pump must not operating properly IF the Roush cylinder temp readings are equal to the actual IAT2 temps.

Does anyone know if these are the same?

Cylinder head temps aren't related to the intake temps (well, they are, but mostly engine cooling). How are you checking your IAT2 temps?

I do not have any way to check my IAT2. How do I do this?

You'll need an OBD bluetooth adapter and you can use the Torque app on your phone.

Don't know how much this actually helps but it's part of the roush max cooling upgrade

I bought it but just for the looks lol

The fenders are hollow. There's only an inch or so slot for the air to go through from the engine bay. They do look neat though

Would cutting a hole in the fender liner help?

Maybe but this might help also.

I ordered the Fi Interchiller, Stage 1. What temps are you getting with normal cruising? Even with a bigger heat exchanger with 2 fans (VMP) I'm 30-40f over ambient. Hoping the interchiller will make a big difference

I have the same FI Interchiller. In the summer stays 87 or below during cruising. Recovers very fast.

You've just made me very happy. Also ordered a blanket and spacers

I bought this ODB reader to find my IAT1 and IAT2 temps. Can’t find them. Help!

You need to buy the Fusion app to go along with it..Then you will see them available and can mark them to come up on your phone.
